Starting thread with non static member function

Suppose we have a class Task, which has non static member function execute() i.e.

1 2 3 4 5

class Task { public: void execute(std::string command); };

Now we want to start a thread which uses execute() function of the class Task as thread function.

As execute() is a non static function of class Task, so first of all we need a object to call this function. Let’s create an object of class Task i.e.

1	Task * taskPtr = new Task();

Now let’s create a Thread that will use this member function execute() as thread function through its object i.e.

1 2	// Create a thread using member function std::thread th(&Task::execute, taskPtr, "Sample Task");

Here in std::thread constructor we passed 3 arguments i.e.
